Easy company to order from. I'm using the test tubes to put in containers I use for my houseplants growing in water. The tubes came well wrapped for no breakage!

These test tubes are exactly what I needed to fit in my vase. This is the only company I found that was able to sell them individually and at a reasonable price. I purchased 10 or so and all arrived well packaged and good quality. Thank you so much!

Love the durability of these large test tubes. Great to be able to purchase individually for craft projects and horticulture displays. Competitively priced and shipped promptly. I purchase all my lab glass from Indigo!
